ABSTRACT:
An endoprosthetic bone joint device for the talo-navicular joint comprises two generally similar components each of disc form with one face curved to define a bearing surface and the other face provided with an elongated, relatively shallow, relieved configuration extending across the latter face, the components differing by having complementary bearing surfaces of respectively convex and concave shape. The bearing surface shapes are suitably spherical and the relieved configurations provided by a longitudinally tapered rib with undercut side faces. In use, the joint is approached from above, the bones formed with downward slots to receive the component ribs by translation, and the components with convex and concave bearing surfaces respectively cemented to the talus and navicular.
